  • Meter verification method and apparatus
    Patent number: 5284770
    Abstract: A method and apparatus for verifying the operating accuracy of an instrument (10) for detecting the concentration of a medically significant component of a body fluid. The instrument (10) operates by determining the remission of a reacted chemistry contained on a substrate (106) after the chemistry has reacted with the medically significant component of the body fluid. The instrument (10) includes a radiation source (182), a radiation detector (300) and a pathway (164) from the radiation source (182) to the chemistry (106) and from the chemistry (106) to the radiation detector (300) when the substrate (106) is properly inserted into the instrument (10). The remission of the chemistry (106) determines the radiation detected by the radiation detector (300).
